I have a new shower head, and only get a low pressure cold water to come out.
I have a new shower head, and only get a low pressure cold water to come out. It is a Tuscany shower head/ faucet. I called the company's phone line, and they had me a) remove the rotational limit stop, and b) turn the hot & cold water valves which are on both sides of the ceramic cartridge completely open. Neither of these helped. They then sent me a new ceramic cartridge which I installed, but still get only a low pressure cold water.
There isn't any water valves between the water heater and the shower. I have hot water to both the sinks in the same bathroom as the shower. I have to turn off the water where it comes into the house, in order to work on the shower. I don't want to have to replace the entire shower again to fix this problem. Do you have any suggestions?
